Status Requests
<?> Status Byte
The Verifier responds to a status request <?> with a two character hex value, such as <?/22> .
To determine status:
1. Look up the binary conversion in the table below.
For example, the first hex 2 would be 0 0 1 0 in binary, as read from binary digits 3
through 0; the second hex 2 is also 0 0 1 0 as read from binary digits 7 through 4.
2. Next, enter your binary values from the table below in the
“Binary” column next to the appropriate bit.
3. Under “Binary,” interpret 1 s as true and 0 s as not true. For
example, bit 1 has a 1 in the “Binary” column, indicating
“Command Received”. Bit 5 is also a 1 , indicating that the
“Verifier is in a read cycle”.
<K?> All Status Request
This is the fastest way to learn the Verifier’s current configuration. Sending this request will
return the current settings of all commands, starting with the lowest K command value and
ending with the highest K command value.
<K??> All Descriptor Status Request
This request will return all current descriptors for every K command, starting with the lowest
K command value and ending with the highest K command value.
<K?#> All Range Status Request
This request will return the current settings of all commands within the user-defined range,
starting with the lowest user-defined K command value and ending with the highest user-
defined K command value.
